What kind of offers are you interested in? - I prefer home services, this is totally up to you and what your area of lead Gen is right now (or where you have decided to go)
What is the max volume you can do daily? - Pick a number based on best judgement (this question is most likely a multiple choice of set ranges of volume, so pick one on the lower end.
Where/how would you promote our offers? - Adwords Call Only Ads
What vertical I want to be in? Same as offer question above.
